Summary Introduction

Introduction: The flowering plants are categorized under the group of “angiosperms”. The male reproductive system is called “stamen”. However, the female reproductive system is known as “pistil or carpel”. Pollen grains represents male gametophyte and ovule represents female gametophyte.

Answer to Problem 1TY

Correct answer: The pollen grains of the flowering plants develop “in anthers of the flower”. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

The male reproductive part of the flower is stamen or androecium. Stamen is differentiated into filament and anther at the tip. The formation and development of pollen grains take place in the anther of the stamen.

Option a. is given as “in the anthers of a flower”.

In the anthers of the flower, the development of the pollen grains takes place. Hence, the correct answer is option a.

Reason for incorrect answer:

Option b. is given as “in the carpels of a flower”.

Carpel represents the female reproductive system, which bears female gametophyte and not the male gametophyte. Hence, option b. is incorrect.

Option c. is given as “while being dispersed by winds, water or animals”.

After the formation of pollen grains, it dispersed by winds, water, or animals. This process takes place after the development of pollen grains. Hence, option c. is incorrect.

Option d. is given as, “within ovules”.

The ovules represent the female structure of the female reproductive system of the flower. It gets fertilized by means of pollen grains. Thus, the formation of pollen grains does not takes place inside the ovules. Hence, option d. is incorrect.

Option e. is given as “within pistil”.

Pistil represents the female reproductive system of the flower and it contains ovules. Thus, the development of the pollen grains cannot be possible in pistil. Hence, option e. is incorrect.

Hence, the options b., c., d., and e. are incorrect.

Conclusion

The development of anthers takes place in the anther of a flower.

In a natural population of outbreeding plants, the variance of the total number of seeds per plant is 16. From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
